Oh yeah, by the way. Aluminum ignition key is best alone,keep the rest of your keys elsewhere when racing.LOL. Serious, they do make aluminum ignition/door lock keys.
That's just crazy talk!
I did get my new lightweight Braille battery yesterday.
It's physically 1/3 the size of my Optima, and a 22# savings. The little slip inside stating they tested it showed 762 CCA. That'll work for MY rig.
Now I need to make a much smaller and lighter battery mount and hold-down. The support for the factory battery weighs 18# by itself without the box on top of it.

Which model # did you get? Do you think you could fit 2 of them in a standard size battery box?
I got the BRL-B2317 battery. It's only listed as being 475CCA - but that's at 0° that I will never see. I think you could easily fit 3 of them side by side in a standard size battery box.
I have not tested this setup yet, but on paper it will work awesome.

Don't forget after they throw you out you will have to add about 150lbs back. Front cage, shields and diaper as well as a cert on the chassis. But in till then Have Fun!

It's always something.....
If I end up going to a full cage - I'll have it professionally installed out of ChroMo. The diaper will be a problem. I haven't needed a license for a long time. LOL

Lots of good weight loss ideas. Have you considered any AERO inprovements. FOOD FOR THOUGHT One I have seen is block off your grill area with a thin sheet off lexan use the outer headlight bezel and grill trim screw holes to atatch it cleanly. Drip rail shave would loose weight and decrease drag. Surface mount your front windscreen like old school nascar. A chin spoiler is fairly light and they help significantly. Aero or lack of it is a major loss. ANYTHING to decrease drag WILL increase your trap speed. The way I see this thread is your weight loss will significantly help to 60' and to 60 MPH but after 60 MPH aero is well a HUGE DRAG. Pun intended. EXAMPLE "Speed Increases Drag Since drag depends on velocity squared, driving at 70 mph results in about four times as much drag as driving at 35 mph. Merely increasing speed from 55 mph to 65 mph increases drag by about 40 percent, resulting in a 10 to 15 percent increase in fuel consumption."from online source I have read this thread completly and was inspired to add something positive to assist you in your endevor. GOOD LUCK

Hardtop models are usually stylishly and aerodynamically slippery, but with a little more weight thrown in for the structural integrity supports..... Where as the post door Sedans are usually square and light by nature but with quite a few hot spots as far as un-aerodynamic chambers or dead corners both on the main body and/or underneath. Creating aluminum foils/dams that divert streams of air away or around these pockets will aid in air management and keep the weight down. There's a few air management issues to be dealt with underneath most cars.
As far as my front grille area, I've foiled it with aluminum to completely direct all incoming air through the radiator. Here's my aluminum grille cross support sitting next to the hollowed stock support in the very beginning leading up to my home made foils. Stock one weighed 3-3/4 lbs, mine....1-1/2 lbs. Saved 2-1/4 lbs and no $$ other than some extra aluminum lying around.

Here's the cross support on the car. Directly behind this aluminum support is a void that can be plainly seen and acted as an air funnel leading directly under the hood..... No good as far as aerodynamics. So I created another part to close that gap and side dams that are in place of the inner deleted headlamps and the car ran cooler with no drag under the hood since it has a foil connected underneath the leading edge of the hood. The grille face area still stays open during normal driving and activity at the track.
